Colorado State University researchers have received $1.15 million in federal funds to study how much nitrogen and ammonia are emitted from cattle feedlots, writes the Associated Press.

Feedlots along Colorado's Front Range are believed to be a major source of nitrogen pollution in Rocky Mountain National Park to the west. Biologists say the park's rising nitrogen levels could lead to fish die-offs and other environmental harm.
